三台硅化钼高温电炉微机群控系统

Design of computer group controlling system for high-temperature electric furnace

用一台微机对三台硅化钼高温电炉的控温系统进行了技术改造。针对这种电炉的特点和工艺要求，介绍了硬件组成和软件设计中所考虑的技术问题。改造后，升温时温度误差最大为４℃；保温时温度误差一般为０～１℃。满足了工艺要求，两年来运行一直正常。

A computer group controlling system ho ben adopted in the rebuilding of electric furnace with molybdenum siliCide asheating element. Gab temperature controlling effect has ben obtained,resulting in max temperature difference(TD)of only4℃ during t6mperature rising,and TD of 0-1℃ during temperature holding. The rebuilt furnaces have ben operated normally for two years.
